Mystery Advent Calendar Classroom Set, 24 Christmas Logic Puzzles, Teacher Guide and Answer Key, Classroom License

CLASSROOM SET: 24 CHRISTMAS MYSTERIES with teacher guide, answer key and a classroom license.
One short logic mystery a day for grades 4–8 (ages about 10–14). Instant download, no prep beyond printing.

Every day a small mystery pops up in the snowy town of Snowberry Hollow: a missing gingerbread roof, an empty cookie tin, a silent music box. Students read the story and the clues and fill in an elimination grid until exactly one culprit is left. Every culprit gives the class a secret letter, and the letters tell where the town's golden star is hiding. No crimes and nothing scary. Students practice deductive reasoning, close reading and explaining an answer with evidence.
